Endless Journey, I tried looking it up on the internet for you...looks like what's done normally is you can break a mini just like any other horse, except for riding in saddle...you can saddle break them but just not ride them. If they are quiet enough (as is normally their nature), you can lead them around with a small child on. But most do not get on and train them in the saddle, since they are normally not ridden by adults.
Which is probably why most kids who ride have ponies, not mini's.
